1. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
2. Improving the thermal climate of schools in semi-desert climate : A case study of solutions in La Guajira, Colombia
Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : As the climate changes, hot regions like La Guajira's semi-desert will become even hotter. It is projected that the average temperature in this region will increase by 2.4 ℃ over the course of this century, with a 20 % reduction in precipitation. LÄS MER
3. BSF-colony management efficiency at a large scale fly larvae composting company in Kenya – A field study
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The majority of organic waste globally is either dumped or placed on landfills, which can result in spreading of disease and pests, methane gas emissions, the deterioration of landscapes and odour pollution. One of the solutions to poor organic waste management is to create value from waste. LÄS MER
4. Investigation of the Microstructure of Plastically Deformed Cemented Carbide
Master-uppsats, KTH/MaterialvetenskapSammanfattning : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. LÄS MER
5. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.
